Onboard laptop
I’m new to Expedition and want to buy a laptop for use onboard - any recommendations for something reasonably priced and suitable for running Expedition? Thanks,
Tony

H5000 Target BSP
How do you display Target Boat Speed when you are going upwind, and on the same instrument Polar Boat Speed when you are reaching (say >60deg TWA). My problem is that if I show Polar Boat Speed as the target, then as soon as I am 5deg off TWA, the Polar Boat Speed climbs and gives a false sense of security.
Is there a way of having this Target BSP be sensitive to this situation. (Same applies tacking downwind - I want the TWA and BSP to be optimum rather than 'dance' around as the TWA varies)

Love this setup. A few bugs but 95% suitable for our needs.
How do I keep the BSP TGT at the upwind VMG setting until I reach 60deg TWA?
Do I make a PERF Polar that has the same targets up to 59.9deg TWA?
OR is there a smarter way?

I have a refurbished IBM laptop that I got for under $400CAD that does fine and if it gets broken it is easily replaced. For back up, and to have a tablet on deck, I have a refurbished Panasonic Toughbook FZ-G1 tablet that is fully capable of replacing the IBM laptop. They can be had for $350 to $500CAD. A lot depends on how wet the boat is. I have a dry spot where the laptop lives. A remote screen, mouse and keyboard are in the nav station. If you can find electronics that run on DC voltage you can run them without an inverter and save some power. My laptop and monitor both run on 19V so I made a small 19V bus using a DC to DC converter and wired the power supplies for those devices directly to the 19V bus. The laptop and monitor use less than 3 amps at 12V. A more powerful computer will use more power so only get what you need to run what you need to.
My two cents ;)
